I have an ASA 5525 at our corporate HQ that has one site to site VPN to our back up side currently.

I also have 5 other side location connected with multipoint DMVPN created on the edge routers to those two buildings.

I want to substitute the 5 sites DMVPN with adding 5 ASAs (5510) and have full side to site VPN's, also connected to both of the buildings HQ and Back up/DR.

I’m wondering If this is suffusion set up and is it possible all sides to pass traffic in between one each other ( including voice and data traffic), or my current edge router DMVPN is better solution? And If so is this ASA 5510 is a go fit for my needs?
